Industrial minerals have been mined in Arizona since the dawn of civilization. The applications of these remarkable minerals havebecome increasingly sophisticated until today industrial minerals are displacing metals from many of their traditional uses. Productionof industrial minerals in Arizona has increased steadily because of increasing population and living standards. In 1984, 205 operationsproduced $245 million of industrial minerals. In fact, the tonnage and value of aggregate production are exceeded only by those of copper.In the past 25 years both the kind and quantity of industrial minerals have increased rapidly. The state is an important producer ofaggregate, cement, lime, and gypsum, which are used principally in the construction industry. It also is a major producer of specialtyindustrial minerals such as bentonite, high-purity salt, perlite, and zeolite. Deposits ofhectorite, diopside, and celestite are being developed.Industrial minerals production should continue to increase with an expanding population base unless the resources become unavailablebecause of increases in the acreage of public lands in wilderness and urban areas. Imposition of a single standard for airborne particulateson all minerals that have fibrous varieties could also restrict development of deposits containing acicular minerals.
